[00:41:52 CEST] <Compn> Zeranoe : requested topic no exist
[00:42:24 CEST] <Zeranoe> Compn: looks like he deleted it
[00:42:38 CEST] <Compn> k
[00:43:08 CEST] <Compn> also reddit design has always been bad. also downvoting is not a disagreement button , so it has failed 
[00:44:00 CEST] <Zeranoe> Compn: what do you mean it's not a disagreement button
[00:44:19 CEST] <Compn> downvote is for off topic
[00:44:26 CEST] <Compn> or flames insults etc
[00:44:30 CEST] <Compn> read the rules bro
[00:44:49 CEST] <Compn> no one reads rules, downvote hides actual content, rip 
[01:03:06 CEST] <iive> Compn, that's why you downvote the things you disagree with... :P
[01:04:24 CEST] <iive> imho, slashdot has a lot better system, limit the score to 5, give limited mod points, do moderation on the moderators.
[01:04:39 CEST] <iive> but the problem is, it doesn't scale so well.
[01:07:21 CEST] <thardin> reddit seems to think one moderator per 100,000 users or so is just dandy
[01:08:04 CEST] <thardin> slashdot is old and bitter
[01:08:32 CEST] <iive> a lot of drama has gone around moderators, at least in the reddit past.
[01:12:34 CEST] <atomnuker> hn otoh will shadowban you
[01:12:36 CEST] <kierank> thardin: yeah, too many trump supporters
[01:14:47 CEST] <thardin> pretty much
[01:14:57 CEST] <thardin> sad sack reactionaries
[01:16:36 CEST] <Zeranoe> kierank: on slashdot?
[01:17:55 CEST] <kierank> yes
[01:19:20 CEST] <thardin> try looking at the comments to any article that is anything vaguely progressive
[01:20:57 CEST] <thardin> it seems a bit better now compared to two years ago
[01:26:54 CEST] <Zeranoe> Stay away from /r/The_Donald then
[02:38:13 CEST] <cone-243> ffmpeg 03Carl Eugen Hoyos 07master:e3b339cc92e7: lavf/aviobuf: Increase Statistics verbosity to AV_LOG_VERBOSE.
[02:55:15 CEST] <tmm1> would it be feasible to write an h264 cbs that combined paff fields back together?
[02:57:00 CEST] <nevcairiel> seems kind of awkward to have something that basically un-does the parser
[02:59:38 CEST] <kierank> tmm1: why, some of us want to decode paff fields
[03:00:34 CEST] <tmm1> mediacodec decoder needs them to be submitted together: http://ffmpeg.org/pipermail/ffmpeg-devel/2018-June/231403.html
[03:00:49 CEST] <nevcairiel> mediacodec is such a mess :D
[03:01:18 CEST] <nevcairiel> (and using timestamps for any such things is never the right thing to do)
[03:01:32 CEST] <tmm1> no arguments there, just trying to find the simplest way to get these videos playing
[03:01:32 CEST] <kierank> poc is the only correct way
[03:03:14 CEST] <tmm1> i tried telling the parser not to split them but that didnt work so well, so i guess putting them back together is my only option
[03:03:33 CEST] <tmm1> wondering if i should do that in the decoder or as a bsf
[03:04:20 CEST] <kierank> decoder would be better
[03:04:34 CEST] <kierank> imo from an h264 perspective there's no good reason to combine paff fields
[03:06:19 CEST] <tmm1> when the fields are split, is the pts copied into the first or second field packet?
[03:06:36 CEST] <nevcairiel> first probably
[03:06:47 CEST] <tmm1> it seems like maybe the second? since the packet missing pts is the one with side data
[03:06:50 CEST] <tmm1> https://paste.ubuntu.com/p/M3Qdv498ZD/
[03:06:57 CEST] <nevcairiel> many containers will have timestamps for both fields though
[03:39:11 CEST] <cone-243> ffmpeg 03Carl Eugen Hoyos 07n4.0.1:HEAD: lavf/aviobuf: Increase Statistics verbosity to AV_LOG_VERBOSE.
[04:36:31 CEST] <Compn> iive : moderators are vastly overrated, slashdot and reddit voting are bad. i prefer equal free speech, and ... well... 4chan is the last place to find that haha
[05:37:04 CEST] <Compn> egads
[05:38:04 CEST] <Compn> watching old vhs anime rip
[05:38:09 CEST] <Compn> the audio is so warped !
[05:40:31 CEST] <Compn> thought it was a bug in vorbis decoder for a second :D
[05:52:40 CEST] <cone-243> ffmpeg 03Gyan Doshi 07master:70742f02642c: fate: correct filename references of qt-faststart binary
[13:45:57 CEST] <Shibe> HI, I was wondering how I can compile this simple  code? https://gist.github.com/2bf4664496a0032e6350142a775a504e 
[13:46:02 CEST] <Shibe> primecorder.c:(.text+0x40): undefined reference to `av_hwdevice_ctx_alloc'
[13:46:07 CEST] <Shibe> seems like i'm not giving it the right linker options or i don't have a certain library installed?
[16:20:23 CEST] <cone-914> ffmpeg 03Carl Eugen Hoyos 07master:07d1c4ae3f45: lavc/dpx: Allow packed 12-bit little-endian images.

[23:40:39 CEST] <ramiro> hey, it's been a while that I submitted patchsets to ffmpeg, so I don't quite remember the preferred way of splitting the patches
[23:40:50 CEST] <ramiro> can someone comment on the 4 commits I have in https://github.com/ramiropolla/ffmpeg/commits/intra_penalty ?
[23:42:08 CEST] <ramiro> I'd merge the first three, so I'd end up with "lavu/frame: add mb_types [...]" and "mpegvideo_enc: add intra_penalty [...]"
[23:44:12 CEST] <jamrial> ramiro: no, don't merge them
[23:44:21 CEST] <jamrial> they are split properly as is
[23:45:11 CEST] <jamrial> one adding public enum values, another cosmetic splitting off a function, an ffprobe change and a mpegvideoenc change
[23:46:26 CEST] <jamrial> and for that matter, make the avcodec.h flag 1 << 27 instead, or any free value under 31
[23:46:40 CEST] <jamrial> send the patchset to the ml in any case
